Verified Validator, Delegation, and Reward Processes in PoS System

Abstract

The Proof of Stake(PoS) consensus procedure has become a largely embraced option to the energy-demanding Proof of Work (PoW) contract, guaranteeing the integrity, reliability, and decentralization in the latest Blockchain programme. In a PoS system, staking procedures, validator and delegation functions, reward distribution processes, and governance control operations must be implemented accurately to maintain the system's security. This paper represents the formal verification and validation of Stake Manager key features, as verification of validators and delegators, setting staking tokens, reward evaluation and distribution, and authentication of the owner. This formal model is evolved using the Communicating Sequential Processes (CSP#), and this model is verified concerning critical safety and liveness properties defined in Linear Temporal Logic formula (LTL). The Process Analysis Toolkit (PAT) model checker is used to check these properties, containing accurate reward distribution and exclusion of deadlocks. This verification mechanism ensures that all processes work properly in all feasible execution states. The results ensure the reliability and security of the Stake Manager Contract and emphasize the efficacy of formal verification in securing the PoS blockchain structure.
